syscall/js: handle interleaved functions correctly

Because of concurrent goroutines it is possible for multiple event
handlers to return at the same time. This was not properly supported
and caused the wrong goroutine to continue, which in turn caused
memory corruption.

This change adds a stack of events so it is always clear which is the
innermost event that needs to return next.

Fixes #35256
